Panel data analysis reveals ICT trade and green innovation decrease emissions across 41 Sub-Saharan African nations, suggesting industrial reforms are needed to maximize sustainability gains.
This study investigates how green innovation and industrial structure mediate the impact of information and communication technologies (ICT) on environmental sustainability in Sub-Saharan Africa (SSA). Using panel data from 41 countries between 1998 and 2022, the analysis applies the ARDL model, Pooled Mean Group estimator, and Granger causality tests to explore long-run relationships. Results show that ICT trade flows significantly reduce carbon emissions (CO₂), and green innovation – measured by R&D and patents – leads to reductions in both CO₂ and methane (CH₄) emissions. However, the region's industrial structure, characterized by resource-intensive sectors, weakens these environmental gains. Interaction effects reveal that ICT's environmental benefits are strengthened when combined with higher GDP and FDI levels. These findings highlight the need for structural transformation and investment in sustainable technologies. Policy strategies should integrate ICT development with green innovation and industrial reforms to effectively decouple economic growth from environmental degradation in SSA.
